If a static page is used as the "Posts page", the page's metadata is not availible

[Kelderic]

To Reproduce:

1. Set up a WordPress install.
2. Create a static page.
3. In Settings -> Reading, Set "Posts page:" to your created static page.
4. Give your static page any custom metadata.
5. Attempt to access this metadata via index.php using get_post_meta( $post->ID, ... )

Expected Results:

Selected metadata should appear.

Actual Results:

No metadata appears.

Possible Cause

I think this is because the $post is being replaced by all the posts which are being displayed. We should be able to grab the actual page's metadata though.

Give get_queried_object_id() a shot. In general you'll have a better time with that than global $post.

That does work on index.php, thanks! Also tested get_the_ID(), and it behaves the same as $post->ID:

$post->ID - Replaced by sub loop on index.php.
get_the_ID() - Replaced by sub loop on index.php
get_queried_object_id() - Correctly grabs page's ID on index.php

The Codex documentation of get_post_meta() mentions using $post->ID and get_the_ID(), but not get_queried_object_id(). Adding something there would clarify which to use under different circumstances. Would I need to open a new ticket?

get_the_ID() is indeed a function to be used within The Loop, and since the loop on that page is that of the latest posts, it is returning what it's supposed to.

Codex can be edited by anybody who is logged in. I think it would be sensible to make a note about getting the ID that you want, but perhaps not too specific, and remembering that get_post_meta() is not where you learn about how to get the ID of the object you want.
